And it's not just love that's in the air.
At these southerly latitudes
ocean winds bring rain six-and-a-half days out of seven.
And when it doesn't rain,it snows.
It couldn't be more different
from the cliched image of a South Pacific island.
But surprisingly, what makes Macquarie so rich in wildlife
also benefits other islands in the tropical South Pacific
thousands of miles away.
Macquarie's penguins and seals depend on a cold
nutrient-rich current and that doesn't stop here.
Powered by the strongest winds in the world
the current continues east until it hits the tip of South America
where it's driven northwards.
Over 8,000 miles later
the cold current reaches the equator
and a remote archipelago.
The water has warmed up on the journey north
but it's still cold and nutrient rich.
This has allowed some animals to live here
which you wouldn't normally find this close to the equator.
